Cutting the cable: Wireless charging becomes a reality

Imagine sitting down at work, plopping a mobile device on the desk and having it wirelessly charge itself while, at the same time, synchronizing new data to your PC. In that world, one could also wirelessly charge a phone set on a car's dashboard or armrest while it plays music through the speakers, and never have to search for the one open electrical outlet at the coffee shop or airport. That world may not be too far off for the masses of smartphone, tablet and other mobile device users. With the launch of the Windows Phone 8-based Lumia 920 smartphone last week, embedded wireless charging is hitting the U.S. mainstream. The built-in wireless charging capabilities offered in the Nokia 920 doesn't require that widgets be plugged into the USB port of a smartphone in order to charge it from a magnetic induction power pad. That's the typical wireless charging process today. The Lumia 920 only has to be laid on a power pad to be charged. Charging Pads William Stofega, an IDC mobile device analyst, said wireless charging pad business is currently dominated by Duracell's Powermat technology, which is based on magnetic induction technology, one of two forms of wireless charging.

Already, some products from 120 companies are certified as compliant with the Qi standard. The certified products run the gamut, from the LG Optimus LTE2 and Panasonic Eluga smartphones, to charging pads, gaming controllers, Blu-ray Disc recorders, smartphone docking speakers, automobile phone chargers, alarm clocks, battery packs and charging modules that can be installed in tabletops and furniture. Magnetic induction vs. resonance charging Analysts note, though, that there are some slight differences in the Qi-compliant wireless charging products being developed today.oracle java jdk 7 mac winrar macbook air iconpackager 5 1 full version quake usb adsl modem driver indir google earth for mac os x 10.5.8 free f talk setup winzip for win7 32 bit billiards go locker theme mobile9 style me girl para pc simlab skp md2 exporter for maya dozen games apartment escape 3 walkthrough
